Anybody else think they should have left his knee injured and not try to come up with some way to fix it? First off, it didn't make much sense. Second, it was completely ignored anyway for the last half of the movie. They should have just left the knee injured for the duration of the movie and left it at that. It would add that much more to the first fight scene knowing he's rusty, out of shape, has no purpose to live, AND has a bum knee. And it would make his ascent at the end of the movie that much greater knowing he overcame all that. thoughts?
